At Waseda University, three scientists by the names of Hiroyuki Nishide, Hiroaki Konishi and Takeo Suga have developed a new polymer-based 200 nanometres thick rechargeable battery that incorporates a high charge/discharge capacity, yet it is still durable enough to survive the rigors of recharging. The battery is composed of a redox-active organic polymer film which is then combined with nitroxide radical groups. Unlike some other radical polymer battery solutions that have been developed in the past, this new battery does not have problems with self-discharging. The technology used in the polymer-based battery still is still in the prototype stage, but Dr. Nishide believes that it could find a home in electronic devices within the next three years.
